Hello, I recently bought the ideapad 720s 15 inch, and I've been having a pretty bad experience with the touchpad. I've been looking everywhere for touchpad drivers to update but I haven't had any luck finding some. Would anyone happen to have a fix for the touchpad issues?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Hi,I?ve been looking for a new laptop and I really like the Lenovo Ideapad 720s-15?.But there are so many people talking about issues on the touchpad, such as lagging, on this specific model. I want to know if this problem has been corrected/ is non-existing on new units or there are still people facing this problem.  Kind Regards,David

My touchpad input lags a bit  and scrolling is slow and not consistent. However, if I disable the touchpad with F6 and re-enable it, the touchpad becomes responsive and acts "normal", for a whole minute that is. Then it goes beack t o being slow and unresponsive.

Machine: Ideapad 720S-14IKB Type 81BD The Problem: Randomly (and frequently) the touchpad completely stops functioning. This issue persists even through restarts. After 30-60 minutes it just as unexpectedly starts working again. While it's not working it is 100% non-functional: no mouse shows up on screen, clicking does nothing, swiping does nothing, gestures do nothing. While it is working it is 100% functional: everything works as expected. Things I've already tried:- The 'disable trackpad' function key (trackpad doesn't work in either mode)- Restarting (issue persists through restart)- Updating software (I got latest Windows 10)- Updating firmware (I got latest firmware through Lenovo System Update) Something I noticed while looking for solutions:In 'Device Manager' there is a Trackpad entry in the 'firmware' category, but no driver in the  'Mice and other Pointing Devices' category. I'm not sure if that's normal for this device, and I guess if I have no driver it doesn't explain why my trackpad sometimes *does* work. Also, when looking for a fresh driver download on Lenovo's support page for this machine, there was no entry for trackpad drivers, which struck me as odd. Edit: it has occured to me it's possible this is a hardware issue, so I'll just add that I haven't knocked or spilled anything on the machine either. There was no obvious physical event that preceded the first time this happened.

Hi all,Last October I bought an Ideapad 720s 13IKB, and ever since I always had problems with the touchpad. Sometimes it works, sometimes it gets blocked, sometimes even the cursor doesn't show. I've surfed the Internet and tried all the possible solutions:- Checked for any possible update (both Windows' and the Lenovo's driver);- Uninstalled the driver and rebooted the laptop in order to let it find and install the driver by itself;- Tried several types and versions of drivers;- Rebooted I-don't-know-how-many-times the laptop, hoping that things will get better;- And yes, I checked the touchpad is enabled through the F6 button. I don't think it is a hardware problem, since the touchpad sometimes works I'm sick and tired of this problem, since the computer is new and it costed a little fortune and I need it everyday since I use it for work. Any saviour?

My 720s came with BIOS 6KCN28WW shipped. To stay in touch along the maturing of this still young platform, I upgraded to 6KCN29WW, which is available since last week.I am very pleased, especially about the improved fan regulation.BUT now the touchpad is no longer accessible.The F6/Fn+F6 trick doesn't change anything. And there is also no option connected to input devices in the BIOS setup.Windows doesn't show a mouse cursor at all, until I plug in a USB mouse. Invisible in the device manager, no complaints about missing drivers et al. Same under Linux. I'm puzzled because it has worked with the old BIOS. It is seemingly a firmware issue of the BIOS upgrade, unrelated to drivers. Falling back to keyboard navigation, of course, limits the mobile use of this handsome piece of hardware. So any help appreciated!

Hello, I am posting on behalf of my mom. Similar to some complaints of the Yoga Series her IdeaPad 720s screen is beginning to separate from the panel. Because I seldom ever use her laptop I've not really noticed. While trying to figure out an issue shes been having with some work software (electronic health records), I noticed that the bottom of the panel (in between the rubber seal and hinge area) is slightly exposed and is showing some of the innards of the laptop. She doesn't have the greatest eye sight, so she hasn't noticed. Is anyone else having these issues? Is there a fix or am I going to have to RMA the unit? She's only had the unit for about a month and a half.

There's no problem to use an IPad or my old MacBook, so there's nothing wrong with the network. Must be something wrong with this computer, right? Should I just return it?

Hi, I am writing here because i am concerned by an issue that happened to me today. I came home from school where i was working on my laptop, then once i got home i picked my laptop to work again, but i instantly noticed a big crack on my screen going from the top, near the camera, spreading until it reaches the bottom left of the screen. I decided to call the warranty service from lenovo and explained them the situation, but the customer service representative told me that the warranty doesn't cover physical damage and and that i had to send them the computer so a technician decides whether it is my fault or not... I am very concerned by the situation because i am sure that that crack isn't the result of a bad usage of the product from me, i always take care of it and i have it since almost 2 months.  Considering that, i just wanted to know if something similar happened to other people here and what did the technicians decide ?

Hi, I'm looking at buying this laptop, but i came across a few questions: 1) Can this laptop support up to 32gb RAM as it is mentioned in some youtube reviews? 2) Can this laptop support video through the USB-C port as well, or just data? I'm looking at connecting 2 portable USB-C monitors, 1 through the Thunderbolt port and the other through the normal USB-C port. 3) Is the Thunderbolt port 2 lanes or 4? 4) Is this 4k screen anti-glare as well? 5) How would this 4k screen work connected to 2 FHD portable monitors, in terms of resolution? 6) Is this 4k screen suffering from backlight bleeding as some reviews suggest? Thanks in advance.

A:Lenovo Ideapad 720s 15IKB Touch 4K - specs

Answers to some of your questions: 1) Yes, it supports up to 32GB RAM, however you would need two 16GB 2400MHz DDR4 SO-DIMM modules, which are rather expensive.2) I can confirm, that one USB-C port supports ThunderBolt 3 and DisplayPort 1.2a connection.4) No, it's a glossy panel.6) Most of IPS screens suffers from backlit bleeding problem. It's mostly depends on unit, which you've receive.

I don't know what caused this issue. Note: I bought a mouse so I can use the laptop in a better way and in playing games, but I still use the trackpad.Thanks for your time.

Hello Lenovo Community!  I'm a proud owner of a Lenovo IdeaPad 700-15ISK. I like this laptop alot, even though I only got it a week ago. There is a problem, however. My touchpad is "jumping" at specific time intervals (approx. at a 3 second interval). The "lag" doesn't last more than 0.5 milliseconds, but it's really, really annoying. I tried uninstalling, reinstalling the Synaptics touchpad drivers (I use Windows 10). I tried the ones from Lenovo Support, then the generic ones. I also tried disabling PalmCheck. It didn't work. I tried disabling Realtek Audio Manager, as some people on these forums had a problem with the audio driver causing some kind of conflict, on other laptop models. But that did not work either. Then I installed Ubuntu, and the problem still persisted. I have this annoying touchpad problem even in boot menus! (like Windows/Ubuntu menus, before installing the OS).I opened up a program, which is incorporated into the Synaptics Driver on Windows, called MoodPad, which basically draws a line when you swipe your finger across the touchpad surface. I noticed there are gaps inbetween. I posted some photos to make things more clear. The intervals are fixed, no matter if you swipe the finger across or not. For instance, if you happen to swipe it 2 seconds after the previous "lag" had occured, the next one will occur after 1 second (there is a 3 second interval, as I said before), and so on. Here are the photos from MoodPad.
